Description

A kind of cigaratte filter that extinguishes automatically

Affiliated technical field

The utility model relates to a kind of cigaratte filter that extinguishes automatically, especially can in the extremely short time fire of cigarette end be extinguished automatically, reduces the possibility that fire takes place, and reaches the elimination burning things which may cause a fire disaster, reduces the purpose that fire incident takes place.

Background technology

At present, known cigaratte filter all can not extinguish automatically, just can slowly extinguish when only burning filter tip, causes disaster hidden-trouble easily.So someone attempts the interior water-filling bubble that the appropriate location settles a low temperature fusing point material to make in cigarette, makes stub when firing bubble, burn one's water breaks bubble crust, water is flowed out extinguish stub, be exactly an example as 92233019 patents.Though the cigarette end that this cigarette end can be avoided burning causes fire, complex structure is made trouble.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of cigarette filter, and this filter tip can not only extinguish the fire of cigarette end automatically, does not influence cigarette inherent quality and smoker's custom and mouthfeel again.

The technical scheme that its technical problem that solves the utility model adopts is: filter tip and cigarette connecting portion cigarette increase the isolated circle of fire prevention, and isolated circle is to be made by ultrathin metal or other refractory material.

The utility model beneficial effect is: the isolated circle of fire prevention, and without any side effects to the people, kept former cigarette national standard, and structure is very simple, manufacture conveniently, can not increase cost, realized again making leave cigarette end that after-combustion can be 50 seconds left and right sides fast automatic extinguishing in the time.
